Procedure
4′-[5-(Chloromethyl)-1,3,4-oxadiazol-2-yl]-N-cyclopropyl-6-methyl-1,1′-biphenyl-3-carboxamide (Intermediate 45) (37 mg) and potassium iodide (5 mg) were mixed in cyclohexylamine (2 ml) and DMF (2 ml) and the reaction stirred at room temperature for 18 hours. The solvents were evaporated under vacuum and the residue purified by bond-elut (silica), eluting with an ethyl acetate/cyclohexane gradient. After evaporation of the solvent this gave 4′-{5-[(cyclohexylamino)methyl]-1,3,4-oxadiazol-2-yl}-N-cyclopropyl-6-methyl-1,1′-biphenyl-3-carboxamide.
